This paper reported a headspace gas chromatography (HS-GC) for the determination of denitrifying enzyme activity in soil samples. It was based on measuring the NO 2 signal in a set of closed/air-free vials containing soil samples that incubated at the

Headspace Sampler. The Aijiren Headspace Sampler is based on the architecture of the GC and Automatic Liquid Sampler line of products. Automatic Leak Check ensures each vial is leak-free prior to analysis, with no loss of precision or sensitivity. Hydrogen can be safely used as an alternative carrier gas.

A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

Headspace GC is a sample preparation method for determining volatile compounds in solid and liquid samples. The technique has existed since the late 1950s [12] and is still actively used. With this technique, only the gas phase above the sample is introduced into the GC column.
